A glass sheet (1) having a rectangular shape includes a first side (1y) along a sheet-drawing direction (Y) and a second side (1x) along a width direction (X), and has a length of each of the first side (1y) and the second side (1x) of 1,000 mm or more, and a sheet thickness of 0.1 mm or more and 2.0 mm or less. When five evaluation regions (A) to (E) having rectangular shapes of the same size are sequentially set from one end side in the width direction (X), the absolute value of the average of the front-back deflection differences (X1−X2) of the evaluation regions (A) to (E) in the width direction (X) is 0.06 mm or more and 0.8 mm or less.

This application provides a method and system for real-time calibration and control of the gap between glass calendering rolls. Specifically, this application captures the three-dimensional electric field distribution between the glass calendering rolls, uses the intensity abrupt change points to locate the actual gap between the roll edges and generates an electric field topology map; synchronously acquires orthogonal vibration signals, and converts them into deformation displacement by combining the elastic modulus of the roll body; establishes a dynamic mapping relationship between the electric field topology map and the deformation displacement, and converts the deformation displacement to the same spatiotemporal coordinate system to generate a compensation input set; injects the viscosity parameters of the molten glass, and corrects the deformation using a viscous resistance model; using the corrected deformation as the state and the electric field edge gradient as the reward signal, iteratively generates inertial compensation coefficients; when the rate of change of the coefficients exceeds a threshold, an anti-saturation mechanism is activated and the output is controlled using a dynamic confidence interval, ultimately offsetting the gap drift through the reverse torque of a servo motor. This application eliminates the roll gap drift caused by vibration deformation and molten glass resistance, achieving sub-micron level real-time dynamic calibration.

This invention provides a roll-over monitoring and control system and method for rolled glass rollers, relating to the field of glass manufacturing technology. It includes: multiple temperature monitoring devices arranged along the length of the rolled glass rollers for real-time monitoring of the surface temperature of various areas on the rollers; and a controller that, when any surface temperature exceeds a first preset threshold, controls the roller motor to slow down, increases the cooling water flow of the roller liquid cooling device, and activates the purging device, while simultaneously issuing a roll-over alarm to on-site personnel to remind them to conduct on-site inspections and manual intervention. The beneficial effect is that the handling procedure is initiated at the nascent stage of the roll-over phenomenon, accurately controlling the "golden 5-second" window for fault handling, reserving crucial time for on-site personnel to arrive and implement subsequent manual intervention, thus suppressing the rapid spread and expansion of the roll-over defect from the source, and completely breaking the passive predicament of traditional handling schemes where the fault has already developed to a moderate stage by the time it is discovered.
